Nakajima G8N1 Renzan ("Rita")

Three years after the disastrous failure of the G5N Shinzan,
the Japanese navy again attempted to build a four-engine strategic bomber.
Unfortunately, the prototype of the G8N1 appeared late in 1944, too late to be
put in mass production. In the last months of the war the disastrous situation
of Japanese industry and severe shortages of strategic materials led to the
cancellation of the program, with only four Renzans being completed. One of
those aircraft was destroyed on the ground during an Allied air raid, and after
the war one of the remaining examples was taken to the United States for
testing. The few test flights conducted by the Japanese between American bombing
raids showed that the G8N Renzan was a good plane, and these results were
confirmed by American tests after the war. The aircraft was given the Allied
codename of "Rita".
